C# 在C中的另一个字符串中查找多个值和字符串#

我有一个字符串，有4行：

id  score ping guid       name            lastmsg address               qport  rate
--- ----- ---- ---------- --------------- ------- --------------------- ------ -----
  1     11  45 176387877  Player 1        3250    101.102.103.104:555   3647   25000
  2     23  61 425716719  Player 2        3250    105.106.107.108:555   5978   25000

如何“提取”所有这些值？比如，我想保存“id”、“score”、“ping”、“guid”、“name”等

我在这里找到了一个“GetBetween”函数。我还尝试学习string.Split函数。但我认为我还没有接近我想要归档的内容，而且我还不太理解拆分字符串

我基本上需要删除值之间的所有“”空格，问题是，值的长度可能会更改，例如“name”

有人能给我举个例子，我如何提取这些值吗

提前谢谢

是你的朋友，这很有效

void Main()
{
    // fun fact, the @ in front of the string means it's literal, so you
    // literally get the new lines
    var input = 
    @"id  score ping guid       name            lastmsg address               qport  rate
-- - -------------------------------------------------------------------------
  1     11  45 176387877  Player 1        3250    101.102.103.104:555   3647   25000
  2     23  61 425716719  Player 2        3250    105.106.107.108:555   5978   25000";

    //Gets you each line
    var lines = input.Split('\n');

    // Skip 2 because I doubt you care about the column title 
    // or the row with the dashes
    foreach (var line in lines.Skip(2)) 
    {
      // For each line, Regex split will return an array with each entry
      // Set a breakpoint with the debugger and inspect to see what I mean.
      // Splits using regex - assumes at least 2 spaces between items 
      // so space in 'Player 1' is handled it's a fickle solution though
      // Trim the line before RegEx split to avoid extra data in the split
       var r = Regex.Split(line.Trim(), @"\s{2,}"); 
    }
}

您可以使用正则表达式和命名组执行此操作

样本输入

    var str = @"id  score ping guid       name            lastmsg address               qport  rate
--- ----- ---- ---------- --------------- ------- --------------------- ------ -----
  1     11  45 176387877  Player 1        3250    101.102.103.104:555   3647   25000
  2     23  61 425716719  Player 2        3250    105.106.107.108:555   5978   25000";

正则表达式定义

var regex = new Regex(@"^(?<id>[\d]+)(\s{2,})(?<score>[\d]+)(\s{2,})(?<ping>[\d]+)(\s{1,})(?<guid>[\d]+)(\s{2,})(?<name>([\w]+\s[\w]+))(\s{2,})(?<lastmsg>[\d]+)(\s{2,})(?<ip>[\d.:]+)(\s{2,})(?<port>[\d]+)(\s{2,})(?<rate>[\d]+)$",RegexOptions.Compiled);

输出

ID = 1
Score = 11
Ping = 45
Guid = 176387877
Name = Player 1
Last Msg = 3250
Port = 3647
Rate = 25000

ID = 2
Score = 23
Ping = 61
Guid = 425716719
Name = Player 2
Last Msg = 3250
Port = 5978
Rate = 25000

看起来您可以在空格上拆分第二行并获得每列的长度，然后您可以使用

string.Substring

从每行中提取值，并使用

Trim

删除尾随空格。查看this@vikscool这不是带分隔符的文件。这是一个固定宽度的文件。将整行拆分为一个空格

行。拆分（“”）.Trim（）

。我假设唯一可能包含空格作为值（而不是分隔符）的字段是名称。因此，您可能希望得到第一个和最后4个索引的拆分字符串，中间的任何剩余索引都是字段名的值。

ID = 1
Score = 11
Ping = 45
Guid = 176387877
Name = Player 1
Last Msg = 3250
Port = 3647
Rate = 25000

ID = 2
Score = 23
Ping = 61
Guid = 425716719
Name = Player 2
Last Msg = 3250
Port = 5978
Rate = 25000
